Profile from polyline (but with a twist)

Civil3D
1

Hi eveyone. I need to create a profile from a polyline (the top and bottom of a stairs 2D drawing as shown below).

The problem is that many other commands or graphs can only generate the profile from polyline if there is no vertical components. Is there a way to move the vertices of the vertical lines just a little (i.e. I have done this manually and 0.001 works fine) before generating the profile from polyline?
If I’m not being clear just ask me anything. I will upload the dwg that I’m practicing this. Thanks in advance.

Sorry for the late response. That is a very clever way to edit the geometry of the stair polyline. The polyline to profile part is not working tho. Did you make it work? Thank you so much for your response.

Hi
I already tried it does not work by adding a [AddPVI]

Most likely you need another way
AddFixedTangent Method (Point2d, Point2d)

It will work

I kinda get that I need dto use that method in a Python script, right? But I don’t know how to use Python in Dynamo. Can you guide me on where to learn or what to do to learn? Thanks.

Insha’Allah

Tomorrow
I will try it the second way

If you are trying to show the steps in a profile for visual sakes, perhaps another route would be to develop a script that produces a solid which represents the stairs which can be projected on to the profile view. I’ve used the free LX-Stair add-in (LX-Stair | Autodesk Civil 3D | Autodesk App Store) to make the solid and turned out pretty good. Likely you could do something similar with Dynamo.
